The
hammer-fist strike technique (kentsui-uchi) is a personal
favorite of mine. It is extremely powerful and easy to train.
We often use it for breaking. And in a life or death situation
it can deal a crushing blow. In fact, it has been measured
as the most powerful blow that can be delivered by hand.
If you havent begun training hammer fist yet then
now is a good time to start. Ask your Sensei about training
techniques and opportunities. The training of hammer fist
in kata begins with the naihanchi series. (The Essence of
Okinawan Karate-Do by Shoshin Nagamine, pp 148-163) If your
dojo has a makawara board, train on it every opportunity
you have. The pictures from Master Nagamines book
are excellent reference for training. Remember to squeeze
your fist very tightly upon impact with each strike.
